hi, thank you very much for giving me your answer ,the only thing is that can i do it myself or do i need some machine for resetting them or what have i to do in lay mans terms. I f i can do it myself roughly how much would they cost and what is the proceedur in changing them. today i changed all the oils in the front and back diffs and in the transfer box and gear box ,,, i put in EP 80/90 oil. the oil was good in the diffs and up to the levels but the transfer box was very mucky and cloudy in colour. after i changed the oils i took the jeep for a spin and the 2wd lights were light but when i put it into 4wd high the 4 green lights came on for about 100 mts thenit went into the center orange light flashing (about once every second) so if possible can you tell me if it is the problem you said still or do you think it might be something else.
thank you very much for your help and i will pay you for your help
